Rachel Sussman
For the last 10 years, photographer Rachel Sussman has been traveling the world to photograph the oldest living things on the planet. All the organisms in Rachel's photographs are more than 2000 years old, and among her subjects are a 9000 year old Swedish Spruce tree, a 2500 year old carnivorous fungus, and 5000 year old Antarctic moss. Other photographs show us organisms whose lifespans are hard for us to contemplate. A colony of Aspen trees -- over 80,000 years old -- was around during the time of the Neanderthals. Then there's the Bacteria living in the Siberian permafrost that pre-dates the human race. It was originally discovered by biologists looking for clues to life on other planet. They suspect the bacteria to be about half a million years old.
